Management of Erythematous Breast Masses

Diagnostic Approach

The American College of Radiology recommends ultrasound as the first-line imaging modality for breast masses with signs of inflammation, as it can effectively characterize the mass and guide further management 1, 2, 3, 4, 5, 6
Ultrasound allows for direct correlation between clinical and imaging findings, which is essential for accurate diagnosis of palpable breast masses 3, 5
The National Comprehensive Cancer Network suggests that ultrasound can immediately determine if a breast mass is a fluid collection, solid inflammatory mass, or complex lesion, guiding therapeutic intervention 1, 2, 7

If ultrasound confirms an abscess, the American College of Radiology recommends proceeding with drainage, either through incision and drainage or US-guided aspiration, depending on the complexity of the abscess 5, 7
If ultrasound reveals a solid mass with suspicious features, biopsy should be considered to rule out malignancy 1, 6
If the mass appears benign, follow-up or further characterization may be considered 1

The American College of Radiology notes that acute onset and erythema of a breast mass strongly suggest an inflammatory etiology rather than malignancy 5
Ultrasound can guide therapeutic intervention, such as US-guided aspiration for simple fluid collections or incision and drainage for complex abscesses 2, 7
The National Comprehensive Cancer Network recommends antibiotics as adjunctive therapy for breast masses with infectious or inflammatory etiologies 5, 7

The American College of Radiology recommends ultrasound-guided aspiration for the diagnosis and treatment of inflammatory breast masses, as it allows for both diagnostic sampling and therapeutic drainage in a single procedure 8
Ultrasound-guided aspiration is preferred over mammography for characterizing inflammatory lesions, as it provides more effective visualization and potential therapeutic benefit 8
